Los vecinos Bob y Jim, que viven
en casas contiguas entre sí, usan mangueras de ambas casas
para llenar la piscina de Bob. Saben que tardan 18 horas usando
ambas mangueras. También saben que la manguera de Bob, si
se usa sola, toma 20% menos tiempo que la manguera de Jim
sola. ¿Cuánto tiempo se requiere para llenar la piscina con cada
una de las mangueras sola?

the f

last graph i believe

step-by-step explanation:

worked it out i believe

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
